Abstract
This invention relates to a power factor measurement method of alternating current loop and a device thereof, comprising a digital signal processor, a voltage detector, a current detector, a current measurement element, two plugs, and a short circuit wire. The two plugs are respectively inserted on two AC power sockets of an AC loop, and the short circuit wire is connected therebetween, which is electrically connected with the digital signal processor via the voltage and current detectors. The digital signal processor, via the voltage and current detectors, obtains the voltage of the AC loop and the current of the short circuit wire detected by the current measurement element configured at the short circuit wire. Accordingly, the digital signal processor can obtain the voltage and current values of the AC loop and the phase difference, and the power factor can be calculated and converted from the phase difference.
